ELEVATOR-GATE.

Specification of Letters Patent.

Patented Oct. 22,1912.

Application led April 27, 1912. Serial No. 693,766.

To all whom it may concern:

Be it known that I, FRANK E. SIMoNs, a citizen of the United States,residing at Los Angeles, in the countyT of Los Angeles and State ofCalifornia, have invented a new and useful Elevator-Gate` of which thefollowing is a specification.

My invention relates to a gate for closing the entrance to elevators,and is particularly designed to be used where the overhead trolleysystem of loading and unloading is in use. In such cases the tracks inthe room being arranged overhead extend to the elevator opening in suolia manner as to be in alinement with the tracks on the elevator car whenthe elevator car is stopped at the Hoor. In such construction, elevatorgates'of the class which slide vertically can not be used in asatisfactory manner, and one of the main objects of my invention is toproduce an elevator gate construction which may be conveniently used ininstances where the overhead trolley system of loading and unloading isused.

Referring to the drawings, which are for illustrative purposes only:Figure 1 is perspective view of a portion of a building showing theelevator entrance equipped with gates embodying a form of my invention.the gates being in open position. Fig. 2 is a sectional, plan view of aportion of a room, elevator car, and ent-rance to the same, with thegates in closed position. Fig. 3 is a perspective view of a portion ofthe gate and the operating means therefor on the elevator car. Fig. 4 isan enlarged, detail, sectional view of the spring actuated mechanism ofthe gate. Fig. 5 is a vertical, sectional view of a gate, showing themanner of hanging the same in the gate opening.

1 designates the floor of a building and 2 a wall having an opening 3therein which serves as an entrance to the elevator car indicated at 4.Secured to the top 5 of the opening 3 and ext-ending intothe room are aseries of tracks 6 adapted to support merchandise upon suitable trolleysof any common form, not shown. The elevator car 4 consists of a floor T,a top or roof 8, standards 9 and side members 10. Secured to theunderside of the top 8 of the elevator car are a series of tracks 12indicated in dotted lines. T he tracks 12 are arranged on the top of theelevator car in such a manner that when the Hoor 7 of the elevator caris flush with the floor 1 of the building the tracks 12 register and arein alinement with the tracks 6, so that merchandise may be moved uponand oif of the elevator car by means of the trolleys. not shown, whichrun upon the tracks 6 and 12 respectively. The elevator gate in thepresent instance consists of two gate members 13 and 14, each having avertical supporting standard 15 which eX- tends from the floor to thetop of the opening 3. Extending outwardly fro-1n each standard 15 is aframe consisting of end members 1G, cross members 17 and diagonallyarranged members 18, which frames are so constructed that when the gatemembers are in closed position, the end members 16 of each gate memberare close enough to each other to close the opening 3 so that passage tothe elevator shaft is closed. The gate members 13 and 14 in the formshown are elastically hung in such a manner that when placed in theposition shown in Fig. 1, which is at an angle slightly more than 90degrees with the sill 2O of the floor 1, they remain in such posit-ionuntil they are thrown upon their center. To accomplish this the top 5 ofthe opening 3 is provided with a pin 21 which extends downwardly into asocket 22 secured in the top of the standards 15 ot' the gate members.On the floor 1 is mounted a plate 23 provided with a stud 24 extendingupwardly therefrom. Rotatably mounted on the stud 24 is a frame screws2G. Secured to the end 27 of the frame 25 is a hollow stud 28 adaptedtor slidably receive the end of a rod 29, the outer end of which isprovided with av head 30 having an extension 31 adapted to engage theinner face of a U-shaped member 32 which is fixed upon the stud 24. TheU-shaped member 32 is provided with a pin 33 which is engaged by meansof a seat 34 formed on the head 30 of the rod 29. Mounted on the stud 28and rod 29 is a coil compression spring 35, the ends of whichrespectively engage the head 30 and a nut 3G on the stud 28. With theconstruction of mechanism as just described, the gate. members willassume the position shown in dot and dash lines Fig. 4 unless the gatemembers are moved into the position shown in dotted lines in Fig. 4./Vith the gate in the position shown in dot and dash lines, the spring35 is exerting pressure on the center line of the stud 24, but as thegate swings away from the dot and dash line position the head 23() onthe rod 29 moves out of alinement With the stud 2st., swinging on thepin 33 into the position shown in dotted lines, in which position theline of force exerted by the spring is beyond the center' line of thestud and the gate member, so that the force exerted by the spring tendsto hold the gate in the open position indicated in dotted lines, andWhen in such dotted line position, being beyond 90 degrees from the sillof the floor, the gate is off center and held in such position by thespring, as heretofore described.

Secured to each gate member 13 and 14 is an arm 37, one end 38 of which,when the gate is in open position, extends into the path of cam bars 39and 40 mounted respectively on the ioor 7 and top 8 of the elevator car,there being provided a cam har 39 and L10 at each side of the elevatorcar adapted to engage respectively the arms 37 on the respective gatemembers 13 and 141.

. y The cam bars 39 and 40 are V-shaped so that in going either up ordown the cam bars coming into engagement with the respective arms 37throw the 0ate members 13 and 14 back onto center when the springsbecome active to close the gate.

The gate operates in the following manner: Assunling that in theposition shown in Fig` 1 the elevator car has been started upwardly, thegates remain in the open position shown until the cam bars 39 on thefloor of the elevator car come into engagement with the arms 37 of therespective gate members 13 and 111-. As the upper faces of the cam barsstrike the ends 38 of the arms 37, the ends 3S of the arms are movedoutwardly in the direction of the sides of the elevator car, therebythrowing the gates on the center indicated by dotted lines in Fig. 1,and When so moved the c" gs on the respective gate lnembers exert forceto close the gates into the position shown in full lines Fig. 2, inWhich position the gates remain until manually opened. Should theelevator car be started down- Wardly after the loading operation hasbeen completed, the cam bars 40 on the top of the elevator carWould'come in contact with the arms 37 upon the respective gate membersand operate the same in the manner above described, so that no matterWhether the elevator car is started upwardly or downu'ardly, after theloading operation has been completed, the gates Would be closed as theelevator car passes away from the tloor.

`What l claim is :mq

1. An elevator gate comprising a pivotally mounted gate member, meansfor elastically holding said gate member in closed position when oncenter and in open position When off center, and means on the elevatorcar coacting With said gate member for throwing said gate member oncenter.

2. An elevator gate comprising gate members, means on each gate memberfor elasti- :ally holding said gate members in closed position when oncenter and in open position when off center, and means on the ele'Avater car coacting With said gate members to throw said gate members oncenter.

An elevator gate comprising gate members, means on each gate member forelastically holding said gate members in closed position when on centerand in open position when ott center, an arm on each gate member, andcam means on the elevator car for operating said arms to throw saidgatemembers on center.

4. An elevator gate comprising gate members, means on each gate memberfor elastically holding said gate members in closed position when oncenter and in open position when ott' center, an arm on each gatemember, and cam means on the top and floor of said elevator car adaptedto respectively engage the arms on said gate members.

An elevator gate comprising a plurality of gate members pivotallymounted Within a door opening, a spring on each gate member adapted tohold the gate member ofil center when in open position and to close thegate members when on center, and means on the elevator car adapted tocoact with the gate members to throw the gate members on center to closethc'gates.

ln testimony whereof, I have hereunto set my hand at Los Angeles,California, this 19th day of April, 1912.
